Fedora Update Notification
FEDORA-2016-2df27a2224
2016-10-18 11:24:07.163753
--------------------------------------------------------------------------------
Name : ghostscript
Product : Fedora 25
Version : 9.20
Release : 2.fc25
URL : http://www.ghostscript.com/
Summary : A PostScript interpreter and renderer
Description :
Ghostscript is a set of software that provides a PostScript
interpreter, a set of C procedures (the Ghostscript library, which
implements the graphics capabilities in the PostScript language) and
an interpreter for Portable Document Format (PDF) files. Ghostscript
translates PostScript code into many common, bitmapped formats, like
those understood by your printer or screen. Ghostscript is normally
used to display PostScript files and to print PostScript files to
non-PostScript printers.
If you need to display PostScript files or print them to
non-PostScript printers, you should install ghostscript. If you
install ghostscript, you also need to install the ghostscript-fonts
package.
